Subject [jira] [Commented] (HIVE-1644) use filter pushdown for automatically accessing indexes
Date Tue, 26 Apr 2011 19:15:03 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13025388#comment-13025388
] 

John Sichi commented on HIVE-1644:
----------------------------------

Yeah, when I look in build/ql/tmp/hive.log after running index_auto_test_if_used.q, I see

-jobconf hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat

in the parameters to the spawned job.  So it looks like you haven't got the plumbing all the
way through to the end?

Also, the patch is going to need to be rebased since the commit of HIVE-1803.

> HIVE-1226 provides utilities for analyzing filters which have been pushed down to a table
scan.  The next step is to use these for selecting available indexes and generating access
plans for those indexes.
